BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an organic semiconductor composition, an organic thin-film transistor, electronic paper, and a display device.

2. Description of the Related Art

In apparatuses using a logical circuit such as a thin-film transistor (TFT), RF tag (RFID), or memory used in a liquid crystal display or an organic EL display, an organic semiconductor device having an organic semiconductor film (organic semiconductor layer) composed of an organic semiconductor material is used, because the use of the organic semiconductor device makes it possible to lighten the weight of the apparatus, reduce the cost, and make the apparatus flexible.

In recent years, as expectations for the organic thin-film transistor have increased, the improvement of mobility (particularly, field effect mobility), stability, and the like have been required for the organic thin-film transistor.

Under these circumstances, JP2005-5582A discloses an organic thin-film transistor in which an organic semiconductor layer is formed of a composition containing an antioxidant so as to reduce the oxidation-induced deterioration of the organic semiconductor layer.

SUMMARY OF THE INVENTION

Regarding the manufacturing of the organic semiconductor device, a transition from a manufacturing method implemented by photolithography to a manufacturing method implemented by so-called printed electronics is considered. The printed electronics is a set of methods in which an organic semiconductor film, wiring, and the like are prepared by means of a printing technique such as gravure offset printing or by an ink jet by using a conductive ink, a semiconductor ink, an insulating ink, or the like. When the wiring of the organic semiconductor device is prepared by printed electronics, the use of a metal material such as silver, which exhibits high conductivity and is less influenced by oxidation, is considered. However, the metal material represented by silver has a problem in that ion migration (also referred to as electrochemical migration, hereinafter, simply referred to as “migration”) easily occurs. Particularly, when the metal material represented by silver is used for the wiring in an organic thin-film transistor, the migration developing between wirings (a source electrode and a drain electrode) needs to be inhibited.

As a result of preparing an organic thin-film transistor by using the composition disclosed in JP2005-5582A, the inventors of the present invention found that the mobility of the organic thin-film transistor was greatly reduced. Furthermore, as a result of performing a service life test, the inventors found that the insulation reliability between source/drain electrodes did not satisfy the currently required level.

The present invention has been made under the aforementioned current circumstances, and an object thereof is to provide an organic semiconductor composition, which improves the insulation reliability of an organic thin-film transistor without greatly reducing the mobility of the organic thin-film transistor, an organic thin-film transistor which is prepared by using the organic semiconductor composition, and electronic paper and a display device which uses the organic thin-film transistor.

In order to achieve the aforementioned object, the inventors of the present invention conducted an intensive examination. As a result, they obtained knowledge that, by mixing a fluorine atom-containing compound having a specific structure with an organic semiconductor material, an organic semiconductor composition is obtained which improves the insulation reliability of an organic thin-film transistor without greatly reducing the mobility of the organic thin-film transistor. Based on the knowledge, the inventors accomplished the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a schematic cross-sectional view showing an embodiment of the organic thin-film transistor of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, preferred embodiments of the organic semiconductor composition (composition for an organic semiconductor) of the present invention will be described.

The organic semiconductor composition (hereinafter, simply referred to as a “composition”) of the present invention contains an organic semiconductor material and a fluorine atom-containing compound having a specific structure (hereinafter, simply referred to as an “F-containing migration inhibitor”).

As described above, the composition of the present invention contains the F-containing migration inhibitor which will be described later. It is considered that, for this reason, the composition of the present invention becomes an organic semiconductor composition which improves the insulation reliability of an organic thin-film transistor without greatly reducing the mobility of the organic thin-film transistor.

Hereinafter, by using FIG. 1, the mechanism of the present invention will be specifically described. In FIG. 1, a case of a top contact-type organic thin-film transistor is specifically described.

In FIG. 1, an organic thin-film transistor 10 includes a substrate 11, a gate electrode 12, a gate insulating film 13, an organic semiconductor layer 14, a source electrode 15 a, and a drain electrode 15 b.

When voltage is applied to the organic thin-film transistor 10, due to the action of an electric field, the metal in either or both of the source electrode 15 a and the drain electrode 15 b is ionized. As a result, migration of metal ions occurs between the source electrode 15 a and the drain electrode 15 b, and therefore the insulating properties between the source electrode 15 a/drain electrode 15 b deteriorate. Particularly, it is considered that the ion migration markedly occurs in the vicinity of a surface of the organic semiconductor layer 14, which is positioned between the source electrode 15 a and the drain electrode 15 b, exposed to the outside.

In an organic thin-film transistor (organic TFT) prepared by using the composition of the present invention, the F-containing migration inhibitor has low surface energy. Accordingly, the F-containing migration inhibitor moves to the vicinity of the surface of the organic semiconductor layer and is localized in the vicinity of the exposed surface (surface which does not come into contact with the gate insulating film) of the organic semiconductor layer. Therefore, the F-containing migration inhibitor can inhibit the migration without impairing the mobility. More specifically, in the organic TFT, a large amount of F-containing migration inhibitor is localized in the vicinity of the surface of the organic semiconductor layer that is exposed to the outside. Consequently, the diffusion of the metal ions educed from the electrode can be efficiently inhibited, and the resistance to the migration that occurs when an organic TFT having microelectrodes is prepared is improved. Furthermore, by causing the F-containing migration inhibitor to be localized in the vicinity of the surface of the organic semiconductor layer, it is possible to reduce the amount of the F-containing migration inhibitor reducing the mobility inside the organic semiconductor layer. As a result, it is possible to accomplish excellent performance without impairing the mobility.

The aforementioned mechanism is also supported by Comparative examples 1 to 3 which will be described later. That is, in Comparative examples 1 and 2, in which IRGANOX 1076 as a compound not containing a fluorine atom is contained in the organic semiconductor composition, the compound is not localized as described above and remains scattered inside the organic semiconductor layer. Consequently, the movement of carriers is hindered, and the result of the evaluation of mobility is poor. Furthermore, in Comparative example 3, in which Megafac F-781 as a compound containing a fluorine atom is contained in the organic semiconductor composition, the compound is localized as described above, and the result of the evaluation of mobility is excellent. However, because Comparative example 3 does not exhibit a migration inhibition ability, the result of the evaluation of insulation reliability is poor. From these facts, the present invention is assumed to have the aforementioned mechanism.

Hereinafter, each of the components contained in the composition of the present invention will be specifically described.

In the present specification, an alkyl group may contain a linking group such as —CO—, —NH—, —O—, —S—, or a group obtained by combining these.

<Organic Semiconductor Material>

As the organic semiconductor material contained in the composition of the present invention, it is possible to use a known material used as an organic semiconductor layer in an organic thin-film transistor. Specifically, examples of such a material include pentacenes such as 6,13-bis(triisopropylsilylethynyl)pentacene (TIPS pentacene), tetramethyl pentacene, and perfluoropentacene, anthradithiophenes such as TES-ADT and diF-TES-ADT, benzothienobenzothiophenes such as DPh-BTBT and Cn-BTBT, dinaphthothienothiophenes such as Cn-DNTT, dioxaanthanthrenes such as peri-xanthenoxanthene, rubrenes, fullerenes such as C₆₀ and PCBM, phthalocyanines such as copper phthalocyanine and fluorinated copper phthalocyanine, polythiophenes such as P3RT, PQT, and P3HT, polythienothiophenes such as poly[2,5-bis(3-dodecylthiophen-2-yl)thieno[3,2-b]thiophene] (PBTTT), and the like.

The molecular weight of the organic semiconductor material is not particularly limited. However, in view of the mobility of the organic thin-film transistor, the molecular weight of the organic semiconductor material is preferably equal to or less than 2,000, and more preferably equal to or less than 1,200.

When the organic semiconductor material is a polymer, the molecular weight means a weight average molecular weight.

When the organic semiconductor material is a polymer, the weight average molecular weight thereof is a value that is measured by a gel permeation chromatography (GPC) method and expressed in terms of polystyrene. In the GPC method, the weight average molecular weight is measured by dissolving the organic semiconductor material in tetrahydrofuran and by using high-speed GPC apparatus (HLC-R220GPC) manufactured by TOSOH CORPORATION, TSKgel SuperHZ4000 (manufactured by TOSOH CORPORATION, 4.6 mm I. D.×15 cm) as a column, and tetrahydrofuran (THF) as an eluant.

<F-Containing Migration Inhibitor>

The F-containing migration inhibitor (F-containing anti-migration agent) contained in the composition of the present invention is a compound selected from the group consisting of a compound represented by any of the following Formulae (1) to (8), a polymer compound (X) containing a repeating unit represented by the following Formula (A), and a polymer compound (Y) containing a repeating unit represented by the following Formula (B) and a repeating unit represented by the following Formula (C). The F-containing migration inhibitor is a compound which contains fluorine atoms and inhibits the migration of metal ions.

The content of fluorine atoms (fluorine content) in the F-containing migration inhibitor is not particularly limited and can be appropriately adjusted according to the type of the organic semiconductor material used or the like. However, in view of lowering the surface energy and causing more of the F-containing migration inhibitor to be localized in the vicinity of the exposed surface of the organic semiconductor layer such that the mobility of the organic semiconductor is not impaired, the fluorine content is preferably equal to or greater than 2% by mass and less than 65% by mass, more preferably 5% by mass to 60% by mass, and even more preferably 10% by mass to 50% by mass. Herein, the fluorine content is a value expressed by a ratio (content) of mass of fluorine atoms to the total molecular weight of the migration inhibitor. That is, the fluorine content is a value expressed by {(number of fluorine atoms in compound)×(atomic weight of fluorine)/(total molecular weight of compound)}×100 (%). For example, provided that the migration inhibitor has a total molecular weight of 100 and contains 3 fluorine atoms, the mass ratio (%) of the fluorine atoms to the total molecular weight is 57% by mass which is calculated by {(19×3)/100}×100.

Hereinafter, the F-containing migration inhibitor will be specifically described.
